Are the URL parameters case sensitive?

noob getting up to speed. We're running ArcGIS version 10 Enterprise server and .Net.I created a service from an .msd file. I want to add it to ArcGIS.com.The url appears to be case sensitive. Would someone confirm this yes or no?

In general terms, the URLs are case sensitive. In reality, some part of the URL are not case sensitive, but I think it's easier just to think that it is case sensitive.

As far as the /0 at the end...this indicates a particular layer. As feature services can have multiple layers in them, you can specify an index to get a particular one. If you don't specify the index, you get them all added to the web map.
